Figure 1 is a view in side elevation of a paper roll holder constructedin accordance 1 coil spring 12 is maintained under tensionbe I tween thebearing block 9 and the lower end of the slot 8 to normally urge thishearing block outwardly toward the free ends of the brackets 7. Anelongated roller 13 is journaled between the inner portions of thebrackets 7.

. As best illustrated in Figure 4 of the drawings, a shaft 14 has itsopposite end portion journaled in the upper end portion of the standards3 and has fixed thereon a pair of arms 15. A drop roller 16 is mountedfor rotation on the free end portions of the arms through the medium ofits supporting shaft 17. The standards 3 are also provided, adjacenttheir upper ends, with the inwardly extending brackets 18 between thefree ends of which is rotatably mounted the roller 19. Beneath thebracket 18 are a pair of comparatively long brackets 20 between the freeend portions of which is mounted for rotation the stationary pastingroller 21 through the medium of the shaft 22. The brackets 20 havedepending therefroi'n the ext on 23 in which are journaled the endportions of the horizontal shaft 24 upon which shaft is fixed theintermediate portion of the swing able arms 25 which are disposedbetween the brackets 20. The upper ends of the swingable arms 25 havejournaled therebetween the traveling pasting roller 26 which is ofelongated cylindrical construction similar to that of the previouslydescribed rollers. The opposi'te ends of the swingable arms 25 havemounted thereon the shaft 27 upon the intermediate portion of which ismounted for rotation a disk 28 which is preferably pro vided with arubber periphery. One end of the shaft 24 extends outwardly of thesupporting brackets .20 therefor and has fixed thereon an arm 29 whichsupports the stabilizing weight 30 which, as illustrated in detail inFigure 7 comprises a cylindrical container adapted to be filled with asuitable liquid, such as oil. and is provided with a removable screw cap31. to which is secured the sus pension wire 32.

Thesha-ft 33 upon which the roll of paper 34 is mounted is ournaled inthe recesses or pockets 6 in the standards 3, and the disk 28 is adaptedto engage with the periphery of the roll 34 and is maintained inengagement therewith through the medium of the stabilizing weight 30. Itis further pointed out that the swingable arms 25 are mounted on thesupporting shaft 24 at a point nearest their lower ends and thus theupper ends thereof will overbalance said lower ends for maintaining thedisk 28 against the roll of paper 33.

A pair of levers 35 are pivotally mounted on the shaft 22 which supportsthe stationary pasting roller 21 on the brackets 20 and said leversextend outwardly beyond this pasting roller 21, and are provided attheir outer ends with the upstanding portions 36 adapted to engage thetraveling pasting roller of the opposite unit of the machine in a mannerto raise the said traveling roller out of the way. The opposite endportions of the levers 35 are provided with the lateral extension 37upon which are mounted the upstanding arms 38 upon the upper ends ofwhich are mounted the T-heads 39 for engagement with the supporting arms15 of the drop roller 16. The upper end portions of the arms 38 xtendslidably through the plates 40 which are mounted on the inner side ofthe brackets 18. Expansible coil springs 41 have their opposite endsimpinged on the plates 40 and the T-heads 39 for urging the inner endsof the levers 35 upwardly and consequently the outer ends upon which theportions 36 are mounted downwardly.

As best illustrated in Figure 4 of the drawings. a pair of comparativelyshort shafts have one end journaled in the standards 3 at a pointadjacent the pockets or recesses 6 therein and the roll supporting shaft33. These short shafts are designated by the reference numeral 43 andhave their inner ends supported through the medium of, the angularbracket 44 which extends inwardly from the inner side of the standardsand having downturned end portions provided with a bearing for the saidinner ends of said shafts. The shafts 43 are parallel with the rollshafts An elongated gear 45 is loosely mounted for rotary andlongitudinal movement on each of the shafts 43 and is constantly in meshwith apinion gear 46, see Figure 5, on the roll shafts 33. The gears 45are provided on one side, with a clutch face 46 for engagement with acomplementary clutch face provided on the adjacent side of a beveledgear 47, one of which is fixed on each of the shafts 43. Verticallydisposed shafts 48 are rotatably supported on the standards 3 on theinner sides thereof through the medium of the brackets 49 and 44 at theupper and lower ends. respectively, of said shafts. Each of the shafts48 has fixed on its lower end a beveled gear 50 which meshes with thebeveled gear 47 on the adjacent shaft 43 and beveled gear 51 is fixed onthe upper end of each shaft 48 and is constantly in mesh with a beveledgear 52 one of which is fixed adjacent each end of the shafts 14 uponwhich the drop roller 16 is mounted. A brake drum 53 is fixed on theouter end of each of the shafts 33.

hen the machine is in operation and the parts are in the positionindicated in Figure 1 of the drawings, the roll of paper mounted on theshafts 33 of the unit 2 is exhausted or very nearly so and the followerdisk 28 of this unit has swung inwardly as the diameter of the roll ofpaper has been reduced. A full roll. of paper is mounted in position onthe unit 1 of the machine and the web is trained over the spring tensionroller 11 un- .der roller 13, over the roller '16, under roller 19,,solver the traveling paster roller 26 and vhas its end portion disposedagainst the outer-side of the stationary paster roller; 21.

A suitable adhesive is then applied tothe outer side ofthe endponti-onofthe new roll otpaper. Itis under-stood, of course, that the newro-llof paper is'mounted on theflunit 1- and the web trained ove-r'therollers and mucilage applied thereto before the paper is;exhausted.from-the roll on unit 2. When the paperof the roll on theunit 2 {is ex hausted the swingagbile arms ha ve moved to theposition-indicated Figure land the traveling paster roll on the upperends thereof .swi-ngs towai'd the co-acting stationary. pastingflroll 21onthe' unit 1 and presses the webagainst the end-otthe new roll o swhich the mucilage' or adhesive has been appliedand the two webs ofpaper are thus secured together. The paper from the two unitsis trainedunder the guide roller A from whichit travels to the printing press; Theinitial pull on the paper from the new roll swings thegdrop roller 16downwardly until; the armslwhichsupport said drop roller engagewith theT-head 39 which. is-mounted on the inner end ofthe levers 35 and the:

outerend of each lever is swung upwardly andkicks, the traveling pastingroller of the opposite unit upwardly out of engagement with thepaper'lon the unit upon which the new .roll is mounted anda continuousfeed of paper'to thepressis thus had without the necessity ofstoppingthe same. The spring pressed-rollers 11 which are mountedforlongitudinal movement between the brackets 7 'prevents the webs vfrombecoming torn by sudden jerks or strains by yieldingthereto, as will beapparent The stabilizer weight urgesthe upper portions of the swingablearms 25 outwardly. and downwardly on their supporting shaftsand preventexces-- sive oscillation of these arms One of thevertical shafts48 ofeach unit has a beveled gear 55:fixed to its intermediate portion whichmeshes with aheveledgearht which is fixedon a stub shaft 57 journaledthrough one of the standards.

A paper roll holder forprinting presses I of the character described comprising a pair When thedrop *roller 16 of the unitupon 7 which the new roll-of paper is mountedis swung downwardly by reasonof the initial excessive pull exertedthereon when theweb from said fresh roll adhersto the web of theexhausting 'roll,-the shaft 14 upon which the drop rolleris-mounted-is'rotated and rotary movement isthus imparted to thevertical shaft 48' of that unit through the medium of beveled gears 52and51' an dvthe shaft 33 upon which the freshroll .offpaper is mountedis caused to start to rotate through the medium of the beveled gears50,147, the co-actingclutch elements 46 mounted onthe I gears Hand 45and the gear46 on saidshaft I:

33. In this manner the web from the fresh roll 34 is relieved of theexcessive strain of starting the rotary movement of the full roll ofpaper; The drop roller is then returned paper 34'and the unit 1 is inoperation, the beveled gears 47 and the shafts 43 are permitted to stop"and remainstationary by reason of the one-way clutches provided'by Vthe cooacting clutch vfaces 46 on -the gears and'4 7.
